      I have a DHCP/DHCPv6 based connection with prefix delegation via DHCPv6. Occasionally the ISP has a problem with their DHCP server, which results in pfsense being unable to renew a lease and thus removes the addresses from the WAN interface, and subsequently removes the delegated IPv6 prefix from the LAN interface.

      If i login to the firewall and set it to use static addressing with the same address it had previously, it will continue to work but eventually the ISP will time out the lease and assign the address to someone else.

      What i really want to happen, is for the address and gateway to be kept on the interface unless DHCP assigns a different one. If DHCP fails to respond for whatever reason, it should keep the configuration it was previously assigned until such time as the DHCP server assigns it a new one. It is possible to do this at all?
